Fig. 2 is a plan view of the same in to McCanna, No. 618,628, dated May 1, 1900, 90 section on the line A A of Fig. 1. Fig. 3 is'` for a lubricating pump, is interposed 'bea similar view in section on the line B B of tween the disk 28 and the flanged disk 27, sc- Fig. 1. Fig. 4 is a central sectidn onthe line ciu-edito the shaft 26, so that the intermittent C C of Figs. .2 and 3, and Fig. is a central swinging movementofthe arm31 will betr-ansformed to an intermittent rotary movement in one direction of the shaft 26. vThis shaft 26 has rigidly secured thereon by any desired means two or more eccentric disks 34, depending upon the number of pumps to be op-` erated. These eccentric disks 34 are placed upon the shaft 26 at diderent angular positions, so that the power from shaft 26 will be applied to the yokes 35, which embrace said eccentrics at different times,I so that the stress on the parts will be distributed uniformly. The yokes 35 have their endfs 36 arranged vertically and fitting somewhat accurately in the correspondi'ngly-shaped ways 37, which are formed in the sides of the cup 12, the outer surface of the cup having the projections 38, adapted to accommodate the ways without cutting entirely through the body of the cup. These yokes 35 are held from lateral displacement by means `of the U-shaped channel-pieces 39, which are secured upon the slanting inner edges of the cups between the bearings 37 by means of the set-screws 40, passing through the edge of the cup and into said channel-pieces. Each of the yokes 35 has a vertical ly-reciprocating rod 41 screwed into or otherwise rigidly secured to its upper side and extending up through the bearing 42, formed in the cap 11 of the casing and above said cap, as clearly shown. The upper end of each of the rods 41 is provided with the arm 43, which may be secured thereon in any desired manner and which has an aperture 44 in the end thereof, through which passes the screw-threaded u pper end of the piston-rod 45. 1n the construction herein shown we have employed only one pump in connection with each rod 41; but it will be understood that the part 43 might have as many arms as might be necessary to accommodate any number of pumps that it might be desired to operate from one rod.

The construction of the pump is best shown in Fig. 5, where it will be seen that the piston-barrel 46 is located in the vertical tube 47, that extends through the top plate 48 of the pump, the upper end of the tube 47 being provided with the packing gland 49,' through which the piston 45 reciprocates. Parallel with the tube 47 isanother tube 50, which is connected with the tube 47 by the top plate 43, as well as by the cross-tube 51. The tube 50 has screwed into its lower end the nut 52, u

the top of the aperture passing through this nut furnishing the seat for the check-valve 53, which is preferably of the customary ball construction. This nut 52 may haye screwed into the lower therewith the tube 54, which extends down to the bottom of the cylindrical portion of the cup, so that thc pump can exhaust practically all the contents of the reservoir. .A valveseat 55 is formed in the tube 50 by contractlng its bore just above the place where it is the conical Vthe consequent rate of end thereof or formed integral entered by the cross-tube 51, and the preferably spherical check-valve 56 cooperates with this valve-seat.

The operation of this pumping mechanism will be readily apparent, as while the piston ascends the valve 53 is raised to permit the pump to be filled, while the pressure of the oil above holds the valve 56 closed. As the piston descends the valve 53 is closed and thev -valve 56 is opened, so that the oil forced out of the pump by the piston will ascend into the connecting-tube 57, which is screwed into the upper end of the tube 50 and leads to the discharge-pipe 58. This connection 57 has an opening into the drain-pipe 59 at right angles thereto, the opening of which is closed by the screw-valve 60, which has its preferably conical end 61 cooperating with the seat 62 in the passage leading through the connection 57. The drain-pipe 59 has the'spout 63 leading' therefrom to deliver the oil at any desired position. The connection 57 has itsenlarged upper end screw-threaded on the outside, and the interior of its upper end is of a hollow cone shape, as seen at 65, to cooperate with end 66'of the joint 67, by which the connection -57 is joined to the dischargepipe 58. The nut 68 serves to hold the joint 67 securely upon the connection 57, and to prevent any backward How of the oil through the drain-pipe when it is opened the check-valve 69 is provided and seats itself upon the shoulder formed at 70 by contracting the diameter of the assage through the joint67. The lower end of the discharge-pipe 58, litting into the joint 67, serves to prevent the valve 69 from being forced away from its proper position. When it is desired to ascertain the rate of feed of any of the pumps, all that has to be done is to open the screw-valve 60, when the weight of the oil above the check-valve 69 will hold it closed, and the oil forced out by the pump will be discharged in drops through the spout 63, where they can be readily counted. The top plate 48 may be provided with the ears 71, through which the screws 72 pass to secure the top plate in place over the apertures formed in the cap 11 to admit the pumps.

lThe strainer 73 will be placed in the aperture 74 in the cap-plate aperture the cup is filled.

The piston-rod 45 has secured upon it be.-

'neath the arm 43 the stationary abutment 75, i

and the length of stroke of the piston-rod and feed of the'pump is regulated by the movable abutment 76, which takes the form of a nut and which is secured in any desired position of adjustment by the ylocking-nut 77. If it is desired to throw any of the pumps out of action, it will be readily apparent that all that is necessary is toadjust the nut 76 so far above the fixed abutment 75 that the space between them willexceed the stroke of the rod 41. By bringing the nut IOO IIO

11, through which fraaie? v 76 nearer to the xed abutment 7 5 any desired portion of the stroke of the rod 41 may be utilized.

While we have shown our invention asV embodied in the-'form which we at present consider best adapted to carry out its purposes, it will be understood that it is capable of some modifications and that we do not desire to be limited in the interpretation or" the following claims except as may be necessitated by the state of the art.
